(Issued 935 AM CST Wed Jan 13 2021) Watching some light reflectivities west of Madison, but there is a decent amount of dry air. Would expect some virga, but can't rule out a few flurries or sprinkles. Otherwise it should be a nice day with highs in the mid 30s to near 40. RAH && .SHORT TERM... (Issued 405 AM CST Wed Jan 13 2021) Today through Friday: A warm front will lift across the state today bringing warm air advection along with it. Unfortunately, that advection will come with a price, as we are expected to cloud over again for the daytime hours. Highs today will be in the upper 30s. Clouds will get thicker and lower tonight ahead an approaching cold front in association with a low over south central Canada. Models then depict a cutoff 500mb low diving southeast out of Canada and a sfc low forming along a triple point over Wisconsin during the day on Thursday. This scenario would put us in line for a very quick punch of snow as the sfc low deepens during the late morning hours and then continuing into Thursday evening before dry air moves in aloft. The sfc low is then projected to stack with the cutoff low aloft and spin and meander during the day on Friday while gradually weakening, keeping some lingering light snow showers around. When all is said and done through Friday a wide area of at least 2 inches looks possible for southern Wisconsin, with less by the lakeshore and more inland, north and west of Madison, where wrap around precipitation from the meandering low could potentially add to totals. CMiller && .LONG TERM... (Issued 405 AM CST Wed Jan 13 2021) Friday night through Sunday night: Cutoff energy will continue to slowly push east of the region Friday night into Saturday, with another shortwave progged to dig across the region Saturday night/Sunday. The departure of the cutoff low will bring a break in the on and off snow showers on Saturday, but as this next wave arrives expect additional chances for on and off snow showers through the rest of the weekend. Temperatures look to remain a few degrees above normal for Saturday, with a cool down expected for the latter half of the weekend as stronger cold air advection is progged to increase across the region. This cool down doesn't look like anything outside of the ordinary for this time of year. In fact, this colder airmass will actually bring temperatures back down to near-normal for this time of year, highs in the 20s and lows in the teens for Sunday. Monday through Wednesday: Subsidence behind the departing shortwave looks to bring a dry start to next week, but additional shortwave activity is progged to either clip or rotate down across the region Tuesday/Wednesday. This does look to reinforce the cold air advection across the region early on, so expect the colder conditions to linger into at least Tuesday. By the middle part of next week, Wisconsin looks to be bisected by the lingering colder air across the northern half of the state, with warmer air beginning to advect in across the southern half. Thus, temperatures look to warm a few degrees above normal towards the middle part of next week. Anderson && .AVIATION... (Issued 935 AM CST Wed Jan 13 2021) VFR conditions are expected throughout the day today, ceilings around 10,000 feet are moving in from the west. Could see some virga, otherwise no precipitation is expected. Winds will be from the south to southwest into Thursday. Chances for snow move in late Thursday morning into Thursday afternoon. Expect MVFR to IFR ceilings and visibilities with snowfall. RAH && .MARINE... (Issued 405 AM CST Wed Jan 13 2021) Modest southwesterly wind gusts will be possible over the far northern end of Lake Michigan this morning, and then the southern end of Lake Michigan in the afternoon in association with some warm air advection. There'll be a lull in wind gusts before southerly winds intensify in association with a deepening low pressure system Thursday afternoon CMiller && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
